Hi @sgosaibi,
Starting with IBM XL C/C++ for AIX V13.1 (first available June 2014) compiler filesets are installed with xlc and xlC in their names. In prior versions, compiler filesets were installed with vac in their name, a holdover from when they were marketed as Visual Age compilers. More information can be found here.
The xlccmp packages are the C/C++ compiler filesets, and the xlc ones are the C/C++ runtime filesets.
You may download the 90 day free trial of IBM XL C/C++ for AIX here.
